or, in what case does the ESC lose its calibrations or de- sync?
The problem is this: my Hex's ESCs have simonk firmware, and don't seem to hold calibration for very long. Granted I'm not an expert here and haven't yet flown a great many hours with this copter, but something has caused calibration to be lost in one or more ESCs over time, several times. ALL-at-once re-calibrations NEVER have worked reliably, necessitating calibrating them separately.
I guess i want to know if this is a process that should be included in every preflight or should I reasonably expect it to stick? Or am i obviously doing something that causes re-initiation other than the documented high throttle init?
Does everyone re-calibrate before each flight?
Thanks in advance, as always,
